What is Masseter Botox Treatment?

Masseter Botox treatment helps with both aesthetic and medical issues. It can slim down a square, wide jawline, correct facial asymmetry, and alleviate jaw pain and aches. These symptoms are often related to bruxism, which involves teeth clenching and TMJ (Temporomandibular Joint Disorders).

This is also known as jawline slimming botox as the masseter muscle is reduced in size and action. Moreover, Botox in the masseter muscle benefits facial structure by reshaping the transition from temples to jawlines and neck, enhancing the overall facial contour.

Where is the Masseter Muscle?

The masseter muscle in the jaw region is a critical facial muscle for chewing. It’s known for its feathered pattern and is the strongest muscle in the human body in size ratio, capable of exerting high pressures on the teeth.

What Is Masseter Hypertrophy?

Masseter hypertrophy occurs when the masseter muscle enlarges, typically due to excessive chewing or teeth grinding (bruxism). This enlargement can cause the jawline to appear more prominent and may result in discomfort from increased muscle tension.

Jaw Slimming Botox

Jaw slimming botox often results in a square, pronounced jawline and can sometimes cause facial asymmetry. These changes can affect an individual’s appearance and self-confidence, leading many to seek treatments to achieve a more balanced facial contour.

How To Assess Your Masseter Muscle Size

Place your fingers on the jaw angle and clench your teeth to assess whether you have an enlarged masseter muscle. You should feel the muscle contract and become prominent.

The diagram below helps evaluate the masseter size by comparing the width of the lower face. The masseter muscle size is considered XL if the lower face appears more comprehensive than the upper face (the “inverted triangle of youth”).

What is the difference between Jaw Botox and Jawline Fillers?

Jaw Botox (botulinum toxin) and Jawline Fillers are non-surgical injectable treatments to enhance your facial profile. The procedures are carried out by an experienced doctor at CosmeDocs after a thorough facial assessment of the patient.

Jaw Botox injection is meant to relax the overactive muscles involved in chewing (masseter hypertrophy). It helps to shrink the size of the jaw muscle, also known as masseter muscle hypertrophy, in a few weeks without any surgery.

On the other hand, Jaw Fillers help restore the volume along the jawline where contour and definition have been lost due to age. Many young patients, too, prefer jawline fillers to soften a square appearance and get a non-invasive chiseled facelift in minutes.

Usually, men and women can benefit from both aesthetic treatments at the same time if they desire to instantly improve their facial balance. However, a detailed consultation is crucial before signing up for Botox treatment and nonsurgical jaw enhancement.

Will I have problems speaking and chewing my food after jaw botox injections?

In a word, no. The non-surgical jaw reduction treatment partially relaxes your masseter muscles, causing them to be less active. As a result, your bulky chewing muscle shrinks (masseter muscle hypertrophy) in just a few weeks. However, after chewing, you may experience slight fatigue around the muscle area, but this is merely a momentary event that will subside, usually within a week.

To conclude, a masseter Botox injection will not affect your speech or eating activity in any way. On the other hand, your unbearable jaw pain is significantly relieved.

Does Jawline Botox Hurt?

Botox in masseter is not all painful for the most patients. The reason behind this is that at CosmeDocs, experts usually use a skin numbing agent before injecting Botox (botulinum toxin) to avoid any possible discomfort.

Moreover, we use very tiny needle during the procedure to minimise any painful experience.
Many patients report a mere pinch or prick during the Botox injections and feel slight soreness immediately after the procedure. Nevertheless, that sensation usually goes away on its own with or without icing the treated areas.
